Abusix runs blocklists built from spam traps, honeypots, and behavior analysis, and mail filters use them to block or score incoming mail. Removal is free and fast, and most listings expire within about five days even if you do nothing.
Spam or abuse listings. Your IP hit Abusix spam traps or showed signs of compromise. Fix the cause, then delist.
Policy listings. Your IP has no reverse DNS or a generic one, so Abusix treats it as an IP that shouldn't send mail directly. If it's a real mail server, set proper reverse DNS and request an exception.
Look up your IP at lookup.abusix.com and create a free account; Abusix requires one to stop abuse of the delisting form. Requests are processed immediately and usually show within five minutes.
Mail sent without confirmed opt-in, purchased or very old lists, bounce handling that hits spam traps, compromised accounts, and infected machines on your network.
Generator Labs checks your IPs and domains against Abusix and hundreds of other blacklists, and tells you exactly which list flagged you and when, so you fix the right thing. Free for your first host.
Yes. You only need a free account.
Most expire about five days after the last bad event.
Probably a policy listing. It means the IP shouldn't send mail directly, and it doesn't mean you sent spam.
